Well, that is because that assertion is wrong. pSample can be returned
on timeout when flushing, but it wouldn't contain any data. I assume
this is the bug you're hitting in patch 2, so if it holds a sample
just break, and release all pSamples returned by that function.

Why my commit breaks things? If all sound stops working I'm guessing
it is a sound bug.

Cheers,
Maarten
